The binding sites of Manganese atom in the structure of B-Specific Alpha-1,3-Galactosyltransferase G176R S235G Mutant (Aabb) +Udp (pdb code 2rj5). This binding sites where shown with 5.0 Angstroms radius around Manganese atom. The 2rj5 structure was solved by S.V.EVANS, J.A.ALFARO, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
